GAR RAGE CREMATOR-Y 0R INCINERATOR.

Patented Feb. 22, 1910.

Application filed December 2, 1908. Serial No. 465,595.

To all whom it may concern:

Be it known that I, FRED P. SMITH, a'citizen of theUnited States, residing at Chicago, in. thecounty of Cook and State of Illinois, have invented certain new and use- "ful Improvements in Garbage Crematories or Incinerators, of: which the following is a specification. v

My presentinvention pertains to improvements in garbage-crematories or incinerators, the construction and advantages of which will beflhereinafter set. forth, referencecbeing had to the annexed drawings, wherein:

Figure lvis a vertical longitudinalsec- .tional view of the apparatus; and Fig. 2 a transversenvertical sectional view, taken on the line 2,2of Fig. 1. t

The main object .of the invention is to construct'an apparatus wherein the garbage which is placed upon the main grate or floor may be swept. bynthe flames from one end to the other, and the flames and products of combustion caused to, pass beneath at least onelialf of the floor on their way to the stack.

A further object of the invention is to rovide-a structure wherein the garbage may e divided into two charges and each portion thereofsub ectedto the action of a separate common stack or flue, whereby the wet garbage may be initially dried preparatory to its being burned and operated upon by one 'of the furnacesalone.

'Another object of the invention is to provide fumes furnaces or fires adjacent to each of the main furnaces, whereby the fumes arising from the garbage will be destroyed before they passto the stack.

A still further object of the invention is to provide an additional fumes fire located at the base o'fthe stack in line with a grid or reticulated opening which, by the action ,of the fire, flbecomes hot and serves to de-,

' "stroy the fumes.

In, the drawings .A denotes the main combustion .chamber,located in the upper portion of the body-ofqthe furnace, and B the transversely-extending grate or supporting floor upon which the garbage or other material is dumped and burned. The center of the grate is provided with an opening controlled by a damper C, andthe end bars of the floor or grate adjacent to the damper are raised or elevated to a slight extent above the main line of the floor, in order to prevent the material from working in upon the damper or through the opening when the damper is turned. Thebars at cachend ofthe floor are separated. forming opens ings D, and said bars are likewise stepped down toward furnaces E and F, which are located, respectively, at opposite ends of the structure. Adjacent to each of said fur-' naccs and beneath the floor arc fumes furnaccs G and H, and between said furnaces and the fire-walls I and J are located hearths K and L. There are thus formed beneath the main floor fines or passages M and N, dampers O and P controlling the passage of the products of combustion from said fines into the lower end of the stack Q. The opening in the lower end of the stack is formed by a series of fire-bricks or the like B, so set as to make a series of openings or passages S. A. grate T is located between the fire-walls l and J in line with the lower portion of the reticulated opening formed as just described. Doors will, of course, be formed in the forward or outer whll of the structure, to afford access to the various lows:- Assuniingthat a new charge is introduced into the structure onto the floor B, fires .wiltbe maintained in the furnaces E and F and the damper C opened, while slides O and P are closed: The flames passing from the furnaces E and F will then sweep over the garbage resting upon each end of the floor and pass to the stack through the central opening formed in the floor. A fire will also be maintained upon the grate 'I, which will assist in causing a strong draft through the stack and likewise heat the bricks B so that they will aid the fire upon the grate T in destroying the fumes jarising from the mass of material.

Fires will also be maintained in the f imes dampeil 0 M11 be closed and furnaces G anld'H, if so desired. Aft the material has become sufliciently dried the one of the slidesO 'or P '(say the slide P) will be QPEIlQd- The flames from the furnace E will then ed by the floor, over the furnace F, through the flue N, and over the fumes fire H into the-stack through the reticulated opening.

Fresh garbage may at this time be dumped upon the right hand end of the floor, so

that it will be dried. After the garbage upon the left-hand end of the floor has been burned, the operation 'will'be reversed, the

slide 1 being closed and the slide 0 opened,

, which may pass through the openings D controlling the openin into the fumes furnaces G and H will be consumed therein and assist in maintaining the fires at these points.

Having thus described my invention, what I claim is:

1. In an apparatus of the character specified, the combination of a combustion chamher having a floor extending transversely of the structure and terminating short of the end walls, s'aid .floor having an opening therein at approximately the center thereof; a furnace 1 cated at each end of the floor and at a point below the same; a damper in the floor; a stack communicating with t e space beneath the floor; and a pair of dampers controlling the passage of the products of combustion from the furnaces as they pass beneath the floor to the stack.

2. In an apparatus of the character specified, the combination'of a structure provided with a combustion chamber in the upper portion thereof having a floor extendmg transversely of the structure, said floor having an opening formed in the central portion thereof and the ends of the floor stopping short of the end walls of the structure; a furnace located at each end of the structure in line with the openings formed between the ends of the floor and the walls pass over the entire mass supportlocated portion ofthe structure; a

ing transversely of the structure and stopping short at each end thereof, said floor being likewise provided with a centrallydisposed opening; a furnace located at each end of the structure in line with the openings formed between the ends of the floor and the walls of the structure; a stack opening into the lower portion of the structure below the floor; a damper controlling the central opening formed in the-floor; a pair of slides or dampers controlling the passa e of the products of combustion from he furnaces beneath the floor into the stack; and a furnace located in line with the base of the stack.

4. In an apparatus of the character specified, the combination of a structure provided with a combustion chamber in the 'upper portion thereof having a floor extending transversely of the structure and terminating short of the ends thereof, said floor being likewise provided with a centrally-disposed opening; a pair of furnaces at each end of the structure in' line with the openings formed between the ends of the floor and the walls of the structure; a damper controlling the central opening formed in the floor; a stack communicating through a reticulated opening with the lower portion of the structure beneath the floor; a air of dampers controlling the passa e of lhe products of combustion from tie furnaces beneath the floor into said stack; and a furnace located in line with the lower end of the stack and between said dampers.

5. In an apparatus of the character specified, the combination of a structure provided with a combustion chamber in the u per portion thereof having a floor extendmg transversely of the structure and, terminatin short of each end thereof, said floor being 'htewise provided with a. central] disposed opening;

centrally-disposed opening formed in the floor; a stack'communicating with the lower.

portion of the structure ,beneath the floor through a' reticulated opening; a furnace located at each end ofthe structure in line with the openings intermediate the endsjofthe floor and the walls of the structure and at a point below the level of the floor; a pair of dampers located below the floor and a damper controlling t e controlling the passa e of the produets of In testimony whereof I have signed my Icombustion from the urnaces into the stack; name to this specification in the presence "a grate located in' line with a reticulated of two subscribing Witnesses.
